Application filed. September down form, provides a casingin which the demountable elements ofthje device may be carried.

My invention possessesother ob ects and features of advantage, some of which with the foregoing will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. it is to be understood that 1 do not limit myself to the showing made by the said adopt variations of thepreferred form within the scope of mm invention as set forth in the claims. I

Serial no. 739,767.

the floor of the miter box, the sides ofthe casing the supporting walls for the floor, and the lid of the casing. may be turned bacliwardly against the rear wall ofthe casing to form the rear upstanding wall of the miter box. ieans are provided for demountably securing the movable parts in their respective functional positions, and

flanges 1'? to facilitate securing it to the ends of the casing by suitable rivets, The rear wall 12 is preferably reinforced at its juncture with he bottom by angle braces 18, and is divided in the center by a slot, bridged by the bearing bracket 20' disposed between and rigidly secured to in any suitable manner, such as by rivets, are a plurality of relniorcing plates each having a. tongue bent thru the casing to formthe leaf 23 of a hinge, the other leaf of which s formed by the tongue 26, which extends from the flanged reinforcing rib 28 riveted on the lid 29.

in. order to permit passage of the saw in the miter be form of my device the lid 29 hus pivotally mounted, is formed of two pieces of sheet metal which are held in spaced relation by the hinges and by the bridge The lid may serve as a cover shown in Figure 5, or it may be turned backwardly against the rear wall 12 to form the upstanding rear wall of the miter boXas shown in Figures 1 and 2.

I provide means for holding the lid in this latter position comprising screws 32 with wing nuts 88, and piercing the rear vall 1 2 of'the casing. The screws have fiattened heads 34: to permit passing thru and engagement with the sides of the elongated .slots 36 in the lid. The security of the upstanding wan of the miter box is increased by passing the screws 32 thru the reinforcing plates 22'and the rlbs 28 whichare con- The 11 the ad' iacent ends of is held in the closed position by a screw Set in the wall 16 and having a head 37 flat tened on one side. The outer adjacent corners ot the lid parts are notched to provide a recess 38, so that the lid will pass over the screw head 37, which may then be given a half turn to seat the head on the edges of the notches.

A slideway -11 is mounted on the casing wall 16, and is provided with a plurality of apertures i2, placed at predetermined points. The slideway serves as a mounting for th bracket -23, and on one side has a clamping screw it which impinges upon the lient wear plate and on the other side a spring pressed stop pin A6, for fixing the position of the bracket. The stop pin L6 is adapted to engage in the apertures 42 in the slidcway to accurately position the bracket at predetermined points so that the saw 4:? may be positioned in the box atcertain commonly used angles such as 15, 30 and on each side of the 90 position.

A saw guide socket 51 is carried on the bracket 43 and the saw guide spindle 52 is mounted in the socket 51. The saw guide is of the usual type, and has the adjusting screw 53 for determining the height of the saw from the floor of the miter box. An arm at is provided on the socket adjacent the bracket, and this arm extends under the iioor of too miter box, telescoping with the arm 56 on the bracket 57, pivoted on the bearing 20. insure perfect alinement of the saw guide so that there is no tendency for the saw to jam in the guides, and they also stiffen the saw guides, so as to maintain parallelism between them.

The bracket 57 is demountably held in position on the bearing in any suitable manner such as by the wing screw 58, which is locked by the set screw 59. A saw-guide socket (30 similar to the socket 51 is fixed in the bracket 57, and contains a spindle 61 similar to spindle The miter saw may be placed in the saw-guides, adjusted and set at any desired angle, and used in the customary manner. A protective layer 62 of wood, leather, or other non-metallic material, is preferably secured to the outer surface 01 the bottom wall 11, by means of screws (33.

My invention provides a compact casing oi relative y small compass in one form, and a large and accurate miter box in another lorm. It is particularly valuable to carpcnters and interior wood workers who are constantly moving from one job to another. It is conveniently transported, and since the dcmountable parts are all carried in the closed casing, itcan be quickly set up, when needed.

I claim:
